Application filed January 12, 1916.

switch stands of that class which is more commonly employed in rail-road yards of the larger towns, and the object of my invention is to provide a rail-road switch which shall embody simple mechanism whereby it can be actuated with more ease and certainty to move its associated railpoints and secure them at required positions for switching a train than is possible with switches heretofore employed. I accomplish this object by devices illustrated in the accompanying drawings wherein- Figure 1 is a view in side elevation of a structure embodying my invention; Fig. 2 is a plan view of the same, and Fig. 3 is a view of the same in vertical section on broken line m, of Fig. 2.

Referring to the drawings, throughout which like reference numerals indicate like parts, 4 and 5 are supporting timbers which preferably consist of extended portions of two rail-road ties of an adjacent rail-road track (not shown) with which my invention is associated, and upon the top surfaces of said timbers 4 and 5 are secured by bolts 6 two iron bars 7 and 8 which are. disposed transversely in parallel with each other to extend between and unite said timbers 4 and 5 to form a rigid support for operative parts of my invention.

Two bearing brackets 9 and 1() are disposed to be parallel with and to be spaced from each other to extend from the bar 7 to the bar 8, to the top surfaces of which bars 7 and 8 said brackets 9 and 10 are rigidly secured by bolts 11 and 12 respectively, as more clearly shown in Fig. 2. The corresponding central portions of the bearing brackets 9 and 10 are bent to form upwardly projecting angular portions 13 and 14 respectively, and to the underside of each of said angular portions 13 and 14 is secured as by bolts 15 and 16 respectively, an angular bearing member like the bearing member 17, as shown in Fig. 1. rlhe apex of each of Specification of Letters Patent.

serial No. 71,800.

Ithe bearing members, as the bearing member 17, and the under side of the apex portion of each of the angular portions 13 and 14 are shaped to form a round hole within which holes are rotatably disposed the cylindrically formed journals of a square shaft 18, one end of which projects outwardly from the angular portion 14 of the bearing bracket 10 for a distance that adapts it to be associated with a lever 19, which is mounted thereon and which is secured in its position by a set-screw 20, whereby said lever 19 may be swung over from its horizontal position, shown by full lines, to the horizontal position, shown in dotted lines of Fig. 1, thereby to rotatively move the square shaft 18 through an angular distance of 180 degrees. The free end of the lever 19 is heavily weighted by a weight 21 fixed thereon, which weight 21 is provided with integral projections 22 which serve as a handle by which it may be actuated by ones hand.

On the square shaft 18, in a position between the bearing brackets 9 and 10, is mounted a pinion 23 which is provided with a series of nine teeth which extends throughout only a larger portion of its circumference while the remaining portion 24 of its circumference is provided with a set-screw 25 which serves to fasten said pinion in its position on said square shaft 18, said pinion 23 being so disposed on said square shaft 18 that said remaining portion 24 is disposed to register with the lever 19. A rack-bar 2G is slidably mounted in guides formed on the iron bars 7 and 8 at corresponding points between the brackets 9 and 10 where it registers with the position of said pinion 23 whereby its teeth may engage with the teeth of said pinion 23 thus to adapt it to be moved in a lengthwise direction in response to a rotative movement of said pinion 23, and said rack-bar 26 is slidably confined within said guides by iron straps 27, as more clearly shown in Fig. 3. lThe rack-bar 26 is of such length that it may be moved endwise within its guides for such distance as will permit all of the teeth of the pinion 23 successively to engage with its own teeth, and its end portions 28 and 29 (that project outwardly from the iron bars 7 and 8 respectively) are each bifurcated and provided with a bolt hole whereby either of said end portions 28 and 29 may be pivotally connected to a link, aslinlr Y30, Whose other end may be articulated to a connecting rod, as the rod 31, which may be extended to and connected' with the associated rail-road switch points not shown; thus adapting the structure to be operatively disposed on either side of said associated railroad switch points. Y

Manifestly, in the operation? of the devices shown and described, the lever 19 when disposedVV as shown by full lines in.

will be maintained by the gravity of the weight 21 in an obvious manner.

Changes may be made in the forms, dimensions andv arrangement of parts of my invention Without departing from the spirit thereof.

What I claim is:

In a switch stand, the combination with parallel supporting members, and parallel cross bars mounted upon said members, of a pair of spaced supporting brackets mounted upon the cross-bars and having upwardly bent intermediate portions, bearing members carried by said upwardly bent portions of the supporting brackets, a shaft journaled in said bearing members, a weighted lever on one end of said shaft, a pinion on the shaft, and a rack bar slidably mounted on the cross-bars and engaged by said pinion, said rack bar adapted for connection at either end with a. switch point.

In witness whereof I hereunto subscribe my name this twenty-seventh day of Decelnber, A.. D., 1915.
